French Fridges Freeze: Cyberattack Spoils Groceries Nationwide
14 Oct
Summary
- Hackers remotely controlled refrigeration equipment, causing widespread food spoilage.
- Approximately 700 French food retailers were impacted by the cyberattack.
- The investigation aims to identify victims and the link to reported damages.

Hundreds of French supermarkets experienced widespread food spoilage this week following a sophisticated cyberattack. Hackers remotely accessed and manipulated refrigeration equipment in approximately 700 food retailers across the nation. The perpetrators triggered defrost cycles, causing freezer temperatures to rise and leading to the loss of large quantities of fresh and frozen goods.
French authorities, including the national cyber agency ANSSI, have opened a thorough investigation into the incident. While no group has claimed responsibility, experts suggest the motive may have been mischief or public disruption rather than financial gain. The attack targeted controllers from companies like Danfoss and Copeland, some of which were running outdated software and were exposed to the public internet.
Major retail groups such as Carrefour and Monoprix reported significant impacts, with warnings that damages could amount to millions. While the French Economy Minister assured the public there was no risk of food shortages, he urged enhanced cybersecurity measures across the sector. The incident has intensified concerns about the growing threat of cyberattacks on critical infrastructure.
